HELP!!! trouble removing extra resontor peice on v6

ok i read the diy on how to remove the extra piece by the battery. but it looks like its a little different on the v6. when i looked to remove the bolt that holds the pipe, its in a very awkward position to use a wrench to remove it. has anyone come across this same problem? how did u remove it. i tried to cut the extra plastic piece to remove it but no good. im stuck!! please help.
